BACKGROUND OF THE INVENTION Field of the Invention

The present disclosure relates to mouse, in particular to a pressurepreloaded key responsive mouse click mechanism.

Description of Related Art

A conventional key responsive mouse click mechanism includes a body atleast a switch and at least a key corresponding to the switch. Theconventional key is a strip, an end of the key is fixed on the body, theother end of the key is arranged above the corresponding switch, and auser can click the suspension end to trigger the switch. According tothe aforementioned structure, an elastic resilience force caused by thekey also causes a resistant force against to click, and a gap is formedbetween the key and the switch, there are various type of resistances inthe key stroke, and a resultant force of the elastic resilience forceand self-resilience force of the switch should be conquered at adestination of the key stroke. Therefore, it is difficult anduncomfortable to click.

In views of this, in order to solve the above disadvantage, the presentinventor studied related technology and provided a reasonable andeffective solution in the present disclosure.

DETAILED DESCRIPTION OF EMBODIMENT

According to FIGS. 1 to 4, a responsive mouse click mechanism which isarranged in a mouse for triggering the mouse to send a signal by a useris provided in the present disclosure.

A responsive mouse click mechanism including a body 100, at least a key200 and an elastic member 300 is provided in the present disclosure.

According to the present embodiment, the body 100 is preferably aplastic base and forming a part of the mouse. At least a switch 110 isarranged on the body 100, the switch could be triggered to send acontrol signal. According to the present embodiment, a couple ofswitches 110 the same with each other are preferably arranged on thebody 100, and only one of the switches 110 will be described below. Atleast a pivotal notch 101 corresponding to the switches 110 is definedon the body 100. According to the present embodiment, a couple ofpivotal notches 101 corresponding to the respective switches 110 arepreferably defined on the body 100, and the two pivotal notches 101 ofeach couple are arranged along the same central axis. However, thenumber of the pivotal notch 101 should not be limited to the embodiment,single pivotal notch 101 is effect for pivoting connection.

For example, a double-key mouse including a couple of keys 200 the sameas each other is shown in the embodiment of the present disclosure, andstructures and motions of only one of the keys 200 will be illustratedbelow. However, the mouse could alternative be a single-key mouse orthree-key mouse, and scope of the present disclosure should not belimited to the embodiment. The key 200 includes an extension arm 210, anend of the extension arm 210 is pivotally connected to the body 100, andthe other end of the extension arm 210 is contacted with the switch 110and allowed to be click by a user to trigger the switch 110. Preferably,a pushing block 211 is arranged protruding on a lateral surface of theextension arm 210. According to the present embodiment, the extensionarm 210 is preferably an arc strip, a convex side thereof is arranged atoutside of the mouse, a concave side opposite to the convex side isarranged in the mouse, and the pushing block 211 is preferably arrangedon the concave side.

A pivotal shaft 220 pivotally connected to the pivotal notch 101 isarranged on an end of the extension arm 210 pivotally which is connectedto the body 100, and the pivotal shaft 220 of the key 200 is thereforecoincide with and the central axis of the pivoted pivotal notch 101 toform a coaxial arrangement. According to the present embodiment, acouple of pivotal shafts 220 corresponding to the aforementioned coupleof pivotal notches 101 is preferably arranged on the aforementioned endof the extension arm 210 pivotally connected to the body 100, the coupleof pivotal shafts 220 are arranged at interval and along the samecentral axis, and the respective pivotal shafts 220 are pivotallyconnected with the respective corresponding pivotal notches 101.

The elastic member 300 is connected between the body 100 and theextension arm 210, the elastic member 300 is arranged between thepivotal notch 101 and the switch 110, and the elastic member 300therefore could press the extension arm 210 to load a moment on theextension arm 210, and the extension arm 210 is thereby rotated to applya preload on the switch 110. An elastic member 300 with suitablecoefficient of elasticity could be provided and the extension arm 210thereby provide suitable elastic force to apply a preload on the switch110 without triggering the switch 110. Specifically, the elastic member300 is arranged between the couple of pivotal notches 101 and a contactpoint between the elastic member 300 and the key 200 is located betweenthe pivotal shaft 220 and the switch 110. According to the presentembodiment, the elastic member 300 is preferably arranged biased acentral axis of the pivotal notch 101 toward the switch 110. Therefore,the user could trigger the switch 110 by a slight click onto theextension arm 210. Moreover, the user resists a uniform slightresistance in the click stroke (namely a resultant force of aself-resistance of the switch 110 eliminated by an elastic force causedby the elastic member 300), and the click stroke is therefore smooth.

The elastic member 300 is arranged between the pivotal notch 101 and theswitch 110, and a downward pressure therefore should be loaded on theextension arm 210 extension arm 210 to cause a moment rotating towardthe switch 110. In order to avoid breaking appearance of the mouse, theelastic member 300 should be located under an external surface of themouse, a cup 230 is arranged between the pivotal shaft 220 and the otherend of the extension arm 210. According to the present embodiment, thecup 230 is preferably arranged between the couple of pivotal shafts 220and biased the central axis of the couple of pivotal shafts 220 towardaforementioned the other end of the extension arm 210. The cup 230 isentirely located at the concave side of the extension arm 210, anopening of the cup 230 is substantially located on a surface extendedfrom the extension arm 210. The elastic member 300 is accommodated inthe cup 230 to presses the internal surface of the cup 230, a pressingplate 120 is arranged on the body 100 corresponding to each cup 230, thepressing plates 120 are substantially arranged on the aforementionedsurface extended from the extension arm 210 to cover the opening of thecup 230 and press the elastic member 300. According to the presentembodiment, the elastic member 300 is a cylindrical spring and a pin 121is arranged protruding from the pressing plate 120, the pin 121 isarranged toward inside of the cup 230, the pin 121 is inserted in an endof the elastic member 300 and an internal surface at bottom of the cup230 is pressed by the other end of the elastic member 300.

Moreover, the elastic member 300 presses on the bottom of the cup 230opposite to the opening direction of the pivotal notch 101 and therebypresses the pivotal shaft 220 into the corresponding pivotal notch 101to fix the key 200 on the body 100.

Furthermore, the appearance of the conventional mouse is of a ballshape, the pivotal shafts 220 of the key 200 are usually not horizontalwhen the is placed on a horizontal plane, if an oblique pivotal hole isdefined on the body 100 for pivotal connecting the key 200, and it istherefore complex to design mode or assemble parts. According to thepresent disclosure, the pivotal shaft 220 is pivotally connected to thepivotal notch 101 and therefore could be assembled without alignmentprocess, and it is therefore easy to assemble parts and design mode.

Although the present disclosure has been described with reference to theforegoing preferred embodiment, it will be understood that thedisclosure is not limited to the details thereof. Various equivalentvariations and modifications can still occur to those skilled in thisart in view of the teachings of the present disclosure.
